Hello everyone. Just installed Linux Mint 13 (the Cinnamon version) a few days ago and everything was working great, but suddenly i can't do a clean shut down. Everytime i do it, i get long lines of text an the system never recovers of it, gotta force a shutdown holding the button. There are long lines of text moving fast but i spotted a few lines:Watchdog detected hard lockup on CPU 0 (an later CPU 1, 2, 3, etc.)Pulseaudio taintedBug: unable to handle kernel paging requestcall tracedon't know how to fix it.
